My invention relates to clothes wringers,

Y. and it is my object to provide a wringer rolls thereof.

A furtherv object of my invention is to which is so constructed that thehands of the operator cannot become caught between the provide'a wringerwhich will Ywring clothes having buttons without tearing the buttonstherefrom, or breaking them.

My invention furtherx has for its object to providev a. wringer in whichthe clothes can not become wound about the rolls when passingtherebetween.

A further object of the invention is to provide a wringer in which thenecessity for the ordinary rubber rolls is done away with.

A still further object ot my invention is to provide such a wringer ofsimple, durable and inexpensive construction.

With these and other objects in view, my invention consists in theconstruction, ,arrangement and combination ofthe various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims and illustrated in theaccompanying drawings, in which: j

Fig. 1 is an elevation ot a wringer embodying my invention. Y

- Fig. 6 illustrates a modiied form of my j 'i invention applied to anold wooden type wringer. A

Fig; 7 1s a vertical sectional view taken on the line 7- 7 of Fig. 6.Attempts have been made to remedy the defect in the ordinary wringer,which is 'the liability of the operators hand becoming caught betweenthe rolls thereot.

1n solving the problem thus existing, l

Ahave proceeded with 'the idea that it the wringer rolls could be somounted that they would readily move apart a 'considerable distanceunder the influence of comparatively light pressure, that. it would bepossible for the fingers of an'operator to *come into gcontactsimultaneously withthe meeting surfaces ot the rolls, and that theslight pressure exerted against the finger of the operator would thuscause him to jerh his hand .back involuntarily, and to thereby tree hishand trom between the rolls.

`lin Fig. 1 lt have shown a metallic wringer trame having side posts,10, and connecting arch, 11. 'llhe compression rolls, 12, are mounted inthe same manner asthe ordinary wringer rolls, the upper roll beingadjustable toward the lower roll by means ot hand screws, 13. Since thisconstruction isold in the art, it is not thought necessary to furtherdescribe or illustrate the same. 'llhe rolls, 12 (see Fig. 5)areprovided with flanges, 1 a

'lhe side faces of the posts, 10, are tlattened, as shown in Fig. 2, andare channeled, as at 15, the channels extending vertically thereof. rlhereceiving rolls, 16, are provided at their ends with rollers, 17,journaled thereon by means of ball bearings, 18. Thus, the rolls, 16,are free to, turn in the rollers, 17, and yet are held againstlongitudinal movement, the hub, 19, which forms a ballrace for thebearings, 18, being secured to the rolls, 16, as at 20. The constructionjust described may be provided in the form of anordinary ball bearing. a

The rollers, 17, are received in the channels, 15, and the rollers ofthe lower roll are supported on projecting lugs, 21, in the lower endsof the channels.

A set of rolls, 16, is provided for each side-of the wringer'and theyare connected and held in place by means of endless belts,

` 22, of rubber or the like. rlhe rolls, 12, are

received inside of the respective belts, 22,

.fand by adjusting the rolls toward each other with the hand screws, 13,the belts may be compressed together intermediate their ends. As theclothes are ted into the wringer between the belts the weight of theupper belt acting againstvthe lower belt will produce enough traction tofeed the clothes between the belts. As the clothesapproach the rolls,12, the pressure between the 4belts will be increased, and upon passingbetween the upwardly a considerable distance, that is,

the inclination of thef faces of the posts is such that these faces willbe inclined upwardly and inwardly within a plane normal to the commonplane of the axis of the upper lreceiving and compression rolls. Thus,the

only pressure betweenthe belts during a certain limit of motion of theroll, 16, is the weight of the roller andthe belt and the `tension onthe belts.

Should the operator catch his fingers'bei tween the rolls, 16, therewill be suflicient pressure caused by such weight to inducel him toreact by drawing ,his hand away from the wringer, although the rolls`may be traveling at a considerable speed, and his lingers may havepenetratedl considerably between the rolls, he may still be able towithdraw them without diiiculty.

Buttons on the clothes being fed through the wringer, eyen though theyshould enter the wringer in a vertical position, will be caused to lieflat by the pressure between the belts before they reach the rolls, 12.

It is understood that the snapping of buttons in the ordinary wringer isdue to the buttons becoming wedged between therolls in a verticalposition transvere to the direction of motion of the clothes through therolls. Since the faces of the rolls which engage the buttons arev notparallel to the line of motion of the clothes, there is'little tendencyinthe ordinary wringer to cause the buttons to 1ie,flat, but where theyare carried a considerable distance between two parallel faces, pressingagainst each other, the pressure will turn the buttons in one directionor the other and causerthem to lie flat.

`Should clothes adhere to either of the belts, they will be simplycarried back toward the operator by the broad faces there-v of, and,having been straightened out, will vnot bend again so as to reenter therolls.

Wrapping 1n the ordinary wringer 'takes place because the clothes willencircle the roll before the operator has a chance to'preventre-entrance. l

The rolls, 12, shown in Figs; 1 and 2, are preferably made of solidmetal, but in some lnstances it may be desirable to cover the rolls witha narrow layer of rubber, as shown at 23 in Fig. 6.

The invention can be applied as anffattachment to an old style wringersuch as is` shown in Figs. 7 and 8, the channels, 15, being formed incastings, 24, which are se'- cured to the faces of the.v posts, 10".

The belts, 22, used with such an attachment are of much thinner materialthan those shown in Figs. l, 2 and 4, since the mamie rubber rolls, 25,of the wringer are allowed to remain and the belts simply insertedaround them. The thinness of the belts used with the steel rollers, 12,must be such as to give the required resiliency of contact against theclothes, but the rubber rolls, 25, will supply that resiliency where theinvention is used as an attachment, and the belts need to be onlyv thickenough to stand the wear and strain to which they are subjected.

The lugs, 21a, corresponding to the lugs, 21, of Figs. land 2, areformed as part of the casting, 24.

In the preferred form of my invention, shown in Figs. 1 and 2, I employthe casing, 26, having ears, 27, pivoted to the lugs, 21. The casings,26, serve to protect the rollers, 18, from dust, and are secured inclosed position by means of screws, 28. The inner sides of the casings,26, are slotted, .as-at 31, to receive the rolls, 16.

The rolls, 16, in the modified form shown in Figs. 7 and 8, whichcorrespond lto the rolls, 16, of Figs. 1 and 2, are provided with anges,32, to position the belts, since it would be impractical to put thelfianges on the rollers, 2 Y f Some changes may be made in theconstruction and arrangement ofthe parts ofv my invention withoutdeparting from the real spirit and purpose of my invention, and it is myintention to'cover by my claims any lmodified forms of structure-or useof mechanical equivalents which may be reason# ably included withintheir scope.

' I claim as my invention:

In a wringer, a pair of side posts, cornpression rollers mounted insaid posts and adjustable toward each other, receiving rolls spacedlaterally from said compression rolls and provided with rollers engagingthe faces of said posts to allow said receiving rolls to move apartfreely, and endless belts of compressible materialsupported upon'l saidreceivin rolls to travel therearound, said endless' elts having coactingopposed por: tions received between the compression rolls and adapted tobe compressed therebetween.

2. In a wringer, a pair of posts having' longitudinal channelsin thesides thereof, a

pair of compression rolls supported in said sides and adjustable towardeach other, receiving rolls spaced laterally from said compressionrolls, rollers journaled on the ends reef/,aia

on the sides thereof, compression rolls mounted in said posts andadjustable toward each other, receiving rolls spaced laterally from saidcompression rolls, rollers journaled on the ends of said receiving rollsand received in said channels, and a pair of endless. belts ofcompressible material supported upon said receiving rolls and havingco-acting opposed portions received between the compression rolls andadapted to be compressed thereby.

4. lin a wringer, a frame, a pair of compression rolls mounted in saidframe, a pair of receiving rolls spaced laterally from said compressionrolls, the upper of said receiving rolls having end portions rollablyengaged against said frame for upward movement away from the lower ofsaid receiving rolls, the surfaces of the frame engaged by said endportions being inclined inwardly and upwardly within a plane normal tothe common plane of the axes of the upper receiving roll and the uppercompression roll, and endless belts of compressible material supportedto travel between said receiving and compression rolls in such manner asto provide extending coacting belt portions, the extremity of saidportions between the receiving rolls resting normally in contact witheach otherwithout pressure between the receiving rolls.
